INT2095 Intronic Semiconductor, Inc. Up Interface Transceiver INT2095 Features Description • The Intronic Semiconductor INT2095 is a fully featured replacement for the industry standard Up interface layer-1 device. It supports loop lengths up to 2.0km over AWG24 cable and provides all signal conditioning, equalization and adaptive threshold adjustment to optimize line performance. The backplane interface supports both IOM1 and IOM2 modes and provides access to all subchannels of the interface including B, D, CI and M-channels. Special function pins (X0-X4) and a master clock output are included in the device for integration with other INT2095’s or layer-2 devices. • • • • • • • • Pin-for-Pin replacement for industry-standard PEB2095 part Up to 2.0km line interface performance NT (LT) and TE mode support IOM1 and IOM2 backplane interface modes Special function pins for interface to other INT2095’s or layer-2 devices Custom versions with Intronic core technology Low Power dynamic operation Single 5V supply 28-pin PLCC (standard) package 1 25 5 INT2095V5 11 19 12 March, 2001 18 INT2095 ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings (VSS = 0V, TJ = 250C) Parameter Power Supply Voltage Input Voltage Output Voltage Input Current Output Current per I/O Storage Temperature Symbol Rated Values -0.3 to +7.0 -0.3 to +7.0 -0.3 to VDD -10 to +10 -10 to +10 -65 to +150 VDD VI VO II IO TSTG Unit V mA 0 C Recommended Operating Conditions (VSS = 0V) Parameter Power Supply Voltage Junction Temperature Symbol VDD TJ Rated Values +4.75 to +5.25 -40 to +100 Unit V 0 C DC Characteristics (Over Operating Range) Parameter High Level Input Voltage Low Level Input Voltage High Level Output Voltage Low Level Output Voltage High Level Input Current Low Level Input Current 3-State Output Leakage Current Stand-by Current March, 2001 Symbol VIH VIL VOH VOL II IO IOZH IOZL IDDQ Conditions IOH = TBD IOL = TBD VIH = VDD VIL = VSS VIH = VDD, VIL = VSS Rated Values Min Typ.
